When you add a standalone host already being managed by vCenter Server to a DRS cluster, the host’s resources become associated with the cluster.

You can decide whether you want to associate existing virtual machines and resource pools with the cluster’s root resource pool or graft the resource pool hierarchy.

Note

If a host has no child resource pools or virtual machines, the host’s resources are added to the cluster but no resource pool hierarchy with a top-level resource pool is created.

Procedure

1

Browse to the host in the vSphere Web Client navigator.

2

Right-click the host and select Move To.

3

Select a cluster.

4

Click OK to apply the changes.

5

Select what to do with the host’s virtual machines and resource pools.

■

Put this host’s virtual machines in the cluster’s root resource pool

vCenter Server removes all existing resource pools of the host and the virtual machines in the host’s hierarchy are all attached to the root. Because share allocations are relative to a resource pool, you might have to manually change a virtual machine’s shares after selecting this option, which destroys the resource pool hierarchy.

■

Create a resource pool for this host’s virtual machines and resource pools

vCenter Server creates a top-level resource pool that becomes a direct child of the cluster and adds all children of the host to that new resource pool. You can supply a name for that new top-level resource pool. The default is Grafted from <host_name>.
